BG(Leader of '7 millions years-old')says Sahelanthropus tchadensis is an extinct hominine species that is dated to about 7 million years ago, possibly very close to the time of the chimpanzee/human divergence, and so it is unclear whether it can be regarded as a member of the Hominini tribe.[1] Few, if any, specimens are known, other than the partial skull nicknamed Toumaï ("hope of life").
